Remote for Doorlocks, Trunk..1993 Concorde

I have 2 remotes that don't work anymore for the doorlocks and trunk for a Chrysler Concorde..they used to work, and both have new batteries. I have pried up the dash cover, and see the Receiver, but info I read points to checking the Voltage and Ground connections...but no color codes are given, and I don't know which wires they are. There appear to be 2 connectors, one with about a dozen or so wires, and another with just 2 wires...white with a blk stipe, and I think a Red wire...would anyone know if these are the two that I should be checking? I don't want to blow up any sensors...I don't see any reason why the remotes would have to be reprogrammed...and don't want my elderly mother to be "taken to the cleaners"....so to speak...I am trying to at least check the power and gnd myself first. I also wouldn't know how to reprogram, if someone thinks it necessary...anyone have any info on this problem?
Thanks kindly....
